Improved sensors, instruments, sophisticated control and automation systems are indispensable, in order to achieve the optimum levels of plant efficiency. Critical to the performance of these tools of productivity, are wires and cables, which efficiently transmit signals and data under harsh environmental conditions. Sushil cables pvt. Ltd. Manufactures such data-communication cables. The rs 232/422/423/485, data bus cables, are such data-communication cables. They are produced in a wide range of sizes, insulation materials, shield configurations, jacket materials, armoured/unarmoured to meet the specific applications. All data communication cables are normally shielded-cables, bearing multicore or multipair configurations. The cables are normally provided with an overall shielding by aluminium-polyester tape or a tinned copper braid shield. In applications, where the protection of signal integrity is vital, a combination of foil and braid shield is furnished with, to ensure optimum shield effectiveness. Moreover data-communication cables, can also be provided with individual core or pair screening, where it seems necessary. The cables are available in various conductor sizes, ranging from 26 awg to 22 awg, i.E., 0.14 to 0.34 sq.Mm. The cables are particularly for low capacitance and specific impedances. Twisted pair cables reduces noise interference and hence data speeds are usually higher than those of multicore cables. The cores are normally colour-coded for easy identification. Custom-designed, import substitute cables are also marketed.
